don't diss at text games, you have no idea how gamedev works. writing is not reading. something that takes a minute to read might take hours and hours to write, especially into an existing story with dozens of variations depending on your stats, which can interact in complex and hard to predict ways that may turn into bugs. and there's like 90mb of plain text and packed code in the game. that's like 20 bibles worth of text!
bugfixes get disproportionate treatment in the log because they don't run a risk of becoming a spoiler-heavy detailed walkthrough. it's a bad metric to measure proportion of bugs to new content. and every sufficiently complex system will have bugs. flash was a leaky bucket that adobe gave up trying to fix. a changelog of an unofficial patch to any bethesda game is the size of a book, each. other engines fare not much better, be it unreal, unity, source, godot, twine, etc. - as a rule, fixes outnumber new content descriptions unless either the descriptions are condensed into something like "various bug fixes" or the devs don't care about fixing their buggy shit.
